dc.description.abstract | The study aimed to evaluate the parameters of reproductive traits, specimens’ fertility and
reproductive efficiency observed in Betula pendula populations growing at different types of
sites (zinc-lead heaps, coal mine heaps and unpolluted site). The leaf biomass and the biometric
characteristics of inflorescences and fructifications were identified. Moreover, the biometric
parameters of B. pendula seedlings were evaluated for examined sites. Seed-originated trees
mostly of age 40 were randomly selected and from each tree, a branches from 1.70 m height and
orientation N–S, W–E to the cardinal points of the stem were chosen. In the laboratory, selected
soil parameters, the viability of pollen and the seeding value of seeds were analysed. According to
the multidimensional statistical analysis the populations of B. pendula growing on post-industrial
wastelands represent different morphotypes with lower values of almost all the reproductive traits,
compared to the unpolluted birch population. Such traits as the male:female catkin number ratio and
the non-embryo seed number were positively correlated with the heavy metal content at the zinc-lead
heaps; at the same time these traits were negatively correlated with soil fertility. The fully developed
seed number and the mature female catkin number were strongly correlated with the available
potassium and phosphorus soil content but also with the leaf number on the generative shoots. The
specimens of birch growing in these three habitats did not develop a universal reproductive strategy.
Some differences in fecundity, the condition of seeds and the patterns of seed germination were
found. The resulting seedling survival is determined by the plasticity of biometric traits, sheltered
places for germination, etc. Seedlings that originated from heaps (local gene resources) are more
suitable for use in the reclamation of large amounts of waste. | pl_PL |
